FLUSH VALVE.

Application filed July 11, 1924. Serial No. 725,479.

To all whom it may oomcern:

Be it known that 1, ROBERT O. H. CAMP- BELL, a citizen of U. S. A., residing at J amaica, in the county of Queens and State of New York, have invented new and useful Improvements in Flush Valves, of which the following is a specification.

This invention relates to a flush valve for closets, the general object of the invention being to provide means for lifting the ordinary flush valve in the tank ofi its seat and to hold the water in the tank until the seat is unoccupied.

Another object of the invention is to provide a weight for holding the parts in inactive position with the main valve engaging its seat so as to hold the water in the tank.

A further object of the invention is to so make the device that it can be easily and quickly placed on outfits already installed.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side view with parts in section of the improvement in use.

.Figure 2 is a similar view but showing the parts in raised position.

Figure 3 is an enlarged sectional view of the device itself.

Figure 4 is a rear view of the device.

Figure 5 is a section on line 5-5 of Figure 4.

Figures 6, 7 and 8 are detail views.

In these views, 1 indicates the tank of a closet and 2 the bowl thereof. The tank is connected with the bowl by the L-shaped casing 3 so that the water can pass from the tank to the bowl. A rod 4 is passed through a packing gland 5 which is connected with an extension 6 of the vertical part of the casing and a small rod 7 is screwed to the upper end of this rod 4 to form an extension thereof. A cup-shaped washer 8 is held in place by the disk 9. which is held on the threaded lower end of the rod 7 and in engagement with the upper end of the rod 4 by the nut 10. The upper end of the rod 7 is threaded to receive the threaded socket 11 of a cup-shaped member 12 which is designed to engage the flush valve 13 of the tank 1 to push the same off its seat. This member 12 is held in adjusted position by the lock nut 14. A weight 15 is connected with the lower end of the rod 4 for holding the parts in inactive position and a U-shaped frame 16 is connected with the rod 4 by the set screw 17. Rollers 18 are connected with the arms of the frame 16 by the bolts 19 engaging the sleeves 20 on said arms. A pair of levers 21 are connected with the seat 22 and pass under the rollers 18 so that when the parts are in inactive position the seat will be held in partly raised position.

When the seat is occupied the levers 21 engaging the rollers 18 will cause the frame 16 to be lifted, thus moving the rod 4 upwardly so as to cause the member 12 to engage the valve 13 and push the same off its seat so that water in the tank will flow into the casing 3. This water is prevented from entering the bowl, however, as the valve 8 will be in a position closing the lower end of the vertical part of the casing and thus prevent the flow of water to the bowl. As soon as the seat is left the weight 15 will cause the parts to move downwardly so thatthe valve 8 will be lowered and thus permit the water to flow into the bowl from the tank.

This valve is intended to be used in public buildings, schools and the like and it will insure the flushing of the closet each time it is used. It can be easily placed on installed outfits by simply removing the elbow which connects the tank with the bowl and substituting the elbow-shaped casing and placing the levers on the seat. The parts are ad justable so as to make them fit different types of closets. When the device is used on high tanks which are generally of the siphon type the upward movement of the parts will allow the flush pipe to fill up with water so as to form the long leg of the siphon. This device will insure a positive flush and can be used with high or low tanks. It is automatic in its operation, thus making it desirable for use in schools and the like. It does not depend on the water pressure and the parts are easy of access to make adjustment or repairs. There is only one washer to get out of order and this will last for years. It canalso be used with the regular hand operated device. p

A guiding member 23 is arranged at the lower end of the casingand has the guides 24 thereon for engagement by the arms of the frame 16.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood-that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

lVhat I claim is I In combination with a bowl having a pivoted seat therefor, and a flush tank, a casing connecting said bowl with the flush tank, a packing gland secured to the lower end of said casing, a rod passing through said packing gland, a weight secured to the lower end of said rod, a second rod secured to the upper end of the rod first mentioned, a valve fixed to the rod second mentioned at its junction with the rod first mentioned, a cup shaped member secured to the upper end -of the rod second mentioned and adapted to unseat the flush of the flush tank a U- shaped frame secured to the rod first mentioned adjacent its connection with its weight, rollers on the upper ends of the U- shaped frame, arms extending from the pivoted seat for engaging the rollers to cause movement of the rods for unseating the fiush valve and allowing the valve first mentioned to close the casing upon movement of the seat to operative position and to be unseated upon movement of the seat into inoperative position. I

In testimony whereof I have afiixed my signature.
